It is not likely to be a practical solution for every day use, but it might be very helpful for testing multi-media applications with OSS4 and ALSA. For example:1. SIP Communicator (PortAudio) with OSS4 + ALSA emulation2. SIP Communicator (PortAudio) with ALSA + OSS emulation

There seems to be a great realm for experimenting. For instance, Twinkle SIP Phone works well with OSS4, but it might be interesting to compare its performance OSS4 vs. ALSA on the same computer and on the same system.
